Summary: Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.
What has the highest biodiversity?
Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
Which ecosystem likely has the highest biodiversity?
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
What area has the highest biodiversity quizlet?
Large ecosystems always have higher biodiversity than smaller ecosystems. A large area of a forest will likely have higher biodiversity than a smaller area of the same forest. A half acre of rainforest would likely have greater biodiversity than a full acre of desert.
What does high biodiversity mean?
Biodiversity refers to the variety of life. When biodiversity is high, it means there are many different types of organisms and species. … And every organism plays a unique role and contributes to how coral reef communities survive and function.
What place most likely have low biodiversity?
The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round. However, life does exist in the arctic regions, mostly affiliated with the seas that surround them.
What makes an ecosystem have high biodiversity?
High biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.
Which biome has the highest biodiversity and is the most threatened?
Large-scale land use change is the most serious threat to tropical grassy biome biodiversity globally, according to the study, especially in regions with higher rainfall, which makes intensive agriculture most viable.
Which of the following has the highest biodiversity 200 dolphins?
Which of the following examples illustrates the community with the highest biodiversity *?
Smaller-beaked finches are better suited for eating grasses and small seeds. Larger-beaked finches are better suited for cracking larger seeds and nuts. In 1977 a drought took place and the vegetation of the island was affected by the lack of rain.
What is an example of high biodiversity?
Examples of places with high biodiversity include rainforests and coral reefs, because they have many different species in an area. Less biodiverse areas include deserts, icy areas, and the bottom of the ocean. Organisms do exist in those places, but not as many as places with higher biodiversity.
